Drilling jig for pump body of clutch master cylinder

Abstract

The invention relates to a drilling clamp for a pump body of a clutch master pump. The drilling clamp comprises a base, wherein a left side plate and a right side plate are arranged on the left side and the right side of the base correspondingly and respectively, a lower meshing port is formed in the upper end of the left side plate, a rotating cover is hinged to the upper end of the right side plate, a threaded rod penetrates through the middle of the rotating cover in a thread connection manner, a handle is arranged at the upper end of the threaded rod, and an upper meshing port matched with the lower meshing port is formed in the left end of the rotating cover. According to the drilling clamp, the rotating cover and the left side plate are combined through the upper meshing port and the lower meshing port, and the rotating cover cannot shake vertically; by means of arranged sliding columns, compressed springs and sliding surfaces, the pump body of the clutch master pump can automatically return under the action of the compressed springs on two sides; the left side and the right side of a press frame are supported by corresponding springs respectively, the levelness of the press frame is guaranteed, the press frame is matched with the sliding columns, the compressed springs and the sliding surfaces for use, the pump body of the clutch master pump can be correctly placed in a three-dimensional and omnibearing manner, and the drilling accuracy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of jigs, in particular to a jig for drilling holes in a pump body of a clutch master cylinder. Background technique [0002] The clutch master cylinder is the part connected to the clutch pedal and connected to the clutch booster through the oil pipe. The function is to collect the pedal travel information and realize the separation of the clutch through the action of the booster. Clutches and clutch master cylinders are easily damaged under bad driving habits, such as excessive use, heavy loads and frequent start-ups. People's driving safety. [0003] The clamping method of the clutch master cylinder commonly used in the prior art during processing is as follows: a left baffle and a right baffle are respectively provided on the left and right sides of the arc surface base, and a positioning column is provided on the upper end of the left baffle, so The upper end of the right baffle is hingedly connected ...

AI Technical Summary

Problems solved by technology

The clamping process of the above-mentioned clamping method is complicated. Firstly, it is necessary to ensure that the arc surface of the lower part of the clutch master cylinder is just stuck on the base of the arc surface; , Tighten the inner hexagonal bolts to flatten the clutch master cylinder to prevent excessive errors when drilling the clutch master cylinder, and then adjust the positioning column to prevent the gland from being stuck on the positioning column when tightening the inner hexagonal bolts The upward offset leads to unstable clamping. However, in today's high-efficiency requirements, it is difficult to ensure the placement and clamping accuracy of the clutch master cylinder under the condition of manual adjustment, and the complicated fixing process also reduces production efficiency.
